4. PROBLEM STATEMENTS
Maximum Demand (MD) of electricity in Peninsular Malaysia increasing from
14,245 MW in 2009, 15,072 MW in 2010 and 15,476 MW in 2011 with the
limited generation capacity cropped at 21,817 MW.
On average, an increment of more than 2% is recorded annually to balance the
increasing of electric energy demand from all sectors throughout Malaysia.
(Energy Commission, 2011)
Lighting consumption from total building energy usage is ranging between 13%
- 43% (USEIA, 2011; Yudelson, 2011; IIEJ, 2011; Griffiths, 2010; Saidur, 2009;
Waide, 2006; Chen, 2010, Crisp et al., 1988; Lam and Chan, 1995; Ramatha,
1994)
Artificial lighting is second major sources of electrical energy costs in office
buildings (Energy Commission, 2011).

8. RESEARCH METHODOLOGY
8
The FOC Daylighting components is based on the recommendation made by Stiles et al. (1998),
Andre and Schade (2002), Grise (2002), Hansen and Edmonds (2003), Ghisi and Tinker (2006),
Kandilli and Ulgen (2007), Sansoni et al. (2008), Hammam et al. (2007), Jeong et al. (2009),
Hamzah et al. (2010), Irfan and Seoyong (2012) and Seung et al. (2013) which comprises:
Receiver (Fresnel Lens) Solar receiver with sun tracking system as also selected by Ono and
Cuello (2003), Kandilli and Ulgen (2007), Sansoni et al. (2008) and Couture et al. (2011) in their
research. Fresnel lens is widely used because it gives the good performance at a low cost (Irfan and
Seoyong, 2012).
Fibre Optic Cable (Plastic Acrylic) Using 6 x 10m plastic acrylic type of cable for transmit the light
from the receiver as it most commonly used in fibre optic lighting in terms of tolerable losses at
reasonable cost as also applied by Cariou et al (1982), Jaramillo et al. (1998 and 1999), Ciamberlini
et al. (2003) and Ono and Cuello (2003).
Diffusers (Plastic Acrylic) is chosen due to 2 materials compatibility that connecting the cables-
diffusers. However, very few research in light diffusing system for fibre optic cable daylighting where
started in 2003 by Sapia (Italy) and in 2011 by Patrick et al. (Canada).
10. RESULTS AND ANALYSIS
10
Based on the consideration on solar radiation and external lux intensity in data
analysis also been conducted by A.Zain et al. (2002a), Irfan and Seoyong (2012) for
internal-external lux comparative analysis.
Simplified comparative analysis method was implemented by A.Zain et al. (2002a),
Hein and Chirarattananon (2007) and and Mazran (2010) for heat analysis.
Meanwhile Tsoutsos et al. (2005) who investigated the environmental impact from
solar energy followed by Ghisi and Tinker (2006) when outlined the value of saving
per kWh as per concluded earlier than that by Lancashire and Fox in 1996.

14. RESULTS-Energy and CO2 Saving
14
351 watt is an amount of electrical energy required to
illuminate the room in achieving GBI and MS1525:2007
recommendation of minimum 300 lux based on
simulation. Estimated daily energy required,
E = 351 Watt X 8 hour
= 2,808 Watt hour.
= 2.8 kWh x 33.54 cent/kWh
= USD 0.29 / day, 8 hours of operation.
On environmental savings*, as suggested by Lancashire and
Fox (1996) and Ghisi and Tinker (2006):
*Saving from the installation per
operation day
Environmental
Benefits
680 gram 1,904 gram Carbon Dioxide
(CO2)
5.67 gram 15.88 gram Sulphur Dioxide
(SOx)
2.27 gram 6.36 gram Nitrogen Oxides
(NOx)
Above saving is obtainable by the condition of the
system is working well in suitable weather condition.
15. SIGNIFICANT OF RESEARCH
15
This research related to the encouragement on energy studies especially to meet
MS1525:2007 which focussed on the Renewable Energy (RE) and Energy-
Efficiency (EE) aspect in building design.
This research will conclude the possibility of using fibre optic cable as a light
medium mainly in light distribution strategies thus creating an opportunity for
maximizing the solar daylighting system in illuminating the interior building core
daily.
This research will provide an empirical results of fibre optic as a medium of
daylighting distribution since will cover the most basic parameters especially in
lighting level and human comfort in a building. This method also will create an
awareness among users in taking an advantage from available daylighting in
tropical climate.
16. LIMITATION OF RESEARCH
16
Normal tropical data is collected for 17 days and perception of weather condition
is based on observation only.
Since the research is aiming on the potential of fibre optic daylighting in tropical
climate, the engineering part especially related to construction, development of the
overall system consist of the receiver, light transmission and diffusers will not be
covered in detail under this research.
The benefits of FOC daylighting system is to illuminate interior spaces where there
is no sunlight penetration is possible, research will only consider the total dark
room for test bed.
In addition, the building materials engineering related to the roof, walls, floors and
any other aspect which is not related to research objectives and research questions
above will not be elaborated in this research.
